Abstract : Coaxial cables of semi-air space design were developed for 300C and 500C service, and their excellent performance characteristics and stability demonstrated. Filled Teflon, at 300C, and Refrasil or Quartz, at 500C perform satisfactorily as dielectrics. A laminate tube construction was developed for use as the outer conductor (sheath) at high temperatures. Advantages gained include tougher plating protection, and a minimum metal losses. The new cables are practical to manufacture in lengths up to 100 ft. or more, and can be supplied either with smooth or corrugated outer conductor. The constructions provide communication capabilities in high temperature environments; alternatively, at low ambients they can satisfy high power requirements. Cable fittings of optimum electrical design were developed to provide a sealed system. Pressurizing may be used to augment voltage and power handling capabilities. Cable performance in a nuclear field was shown to be essentially unaffected by the ionizing radiation of the air dielectric. (Author)
